It would possibly be enshittified like others. The whole purpose of decentralization would be broken and it would become one single centralized website.

This is why I advise people to lead people to other instances than lemmy.world. That instance is getting too big and the other instances aren’t. We instead should balance the user count in all instances. And possibly finish the implementation to own content in a decentralized fashion using DIDs. That will need something like the blockchain though, so perhaps we could also have a fediverse coin as a bonus? lol
